1. A vacuum adiabatic body comprising:
a first plate that defines at least a portion of a first side of a wall adjacent to a first space;
a second plate that defines at least a portion of a second side of the wall adjacent to a second space;
a vacuum space provided between the first plate and the second plate;
a support including support plates that maintain a distance between the first plate and the second plate; and
a thermal insulator including at least one radiation resistance sheet provided between the support plates to reduce heat transfer between the first plate and the second plate,
wherein
the support plates include a first support plate that supports the first plate and a second support plate that supports the second plate, and
an area of the second support plate is greater than or equal to an area of the first support plate, and
wherein the radiation resistance sheet includes:
at least one first hole through which a first support bar passes, the first support bar being configured to guide a position of the radiation resistance sheet within the vacuum space; and
at least one second hole through which a second support bar passes, wherein each of the at least one second hole is larger than each of the at least one first hole.
